2024 election updates: Trump, Harris hit more battlegrounds

In remarks in battleground Georgia focused on the economy and the tax code, Trump said dealing with immigration is first step in his economic plan.

In Savannah, Trump again said migrants with legal protected status in Springfield, Ohio, need to be deported and repeated his discriminatory and false argument that undocumented immigrants were stealing jobs from Black and Hispanic communities. He went on to call on local officials to "move the people back to the country from which they came."

Trump spent much of his speech focused on increasing domestic production by tariffing other countries, telling Georgians they soon would be "stealing" jobs from other countries.

"Vote for Trump, and you will see a mass exodus of manufacturing from China to Pennsylvania, from Korea to North Carolina, from Germany to right here in Georgia, they're going to come to Georgia, from Germany and a lot of other places," he claimed.

"I'm outlining today, not only will we stop our businesses from leaving for foreign lands, but under my leadership, we're going to take other countries' jobs. Did you ever hear that expression before? Have you ever heard that? 'We're going to take other countries' jobs.' It's never been stated before. We're going to take their factories," Trump claimed.

The former president also touched on Ukraine, just hours after President Joe Biden urged world leaders gathered at the United Nations General Assembly to never "waver" in support for Ukraine.

"I think that we're stuck in that war unless I'm president. I'll get it done. I'll get it negotiated," Trump claimed -- a campaign pledge he often repeats but offers no specifics on how to accomplish.

Trump then seemingly praised Russia.

"That's what they do, is they fight wars," he said. "As somebody told me the other day, they beat Hitler, they beat Napoleon. That's what they do. They fight and it's not pleasant."

Nebraska Gov. Jim Pillen released a statement Tuesday confirming he has "no plans" to call a special session before the November general election -- meaning that the Republican-led effort to change the state electoral college to winner-take-all is tabled, for now.

"My team and I have worked relentlessly to secure a filibuster-proof 33-vote majority to get winner-take-all passed before the November election," Pillen said. "Given everything at stake for Nebraska and our country, we have left every inch on the field to get this done."

"Unfortunately, we could not persuade 33 state senators," he added.

Pillen specifically cited opposition from state Sen. Mike McDonnell, who on Monday said he would not support such a change before the 2024 election.

The switch would have likely benefited Trump and made the electoral map more difficult for Harris.

Trump is now weighing in on Harris' plans to visit the southern border this Friday in Arizona, labelling the visit as "political" and accusing her of attempting to "con the public" of her border record.

"After almost four years, Border Czar Kamala Harris has decided, for political reasons, that it’s time for her to go to our broken Southern Border. What a disgrace that she waited so long," Trump wrote on his social media, repeating his disparaging rhetoric on migrants.

While Harris has been to the southern border, the trip marks her first visit since lauched her campaign at the end of July.

Trump has made immigration central to his 2024 campaign, pledging mass deportations and a border shutdown among other hard-line policies. He visited the border last month, the same day Harris formally accepted the Democratic nomination for president.

Vice President Harris is planning to visit the southern border during her visit to Arizona on Friday, according to a source familiar.

This would be Harris' first visit to the southern border since she jumped to the top of the ticket at the end of July.

Immigration has been a big issue in the 2024 race, with Donald Trump and Republicans inaccurately calling Harris the "border czar" and blaming her for the border crisis. Harris, in turn, argues that Trump and Republicans are at fault for killing the bipartisan border bill earlier this year.

Harris has overseen the Biden administration's efforts to address the root causes of migration as vice president, and visited the border in 2021, after she came under fire for not having done so.
